Hello everyone, I got the ebook version of this gem and would love to get the paperback soon but knowing release date is important for me and here’s why: I am not in USA but will be the 2nd week of September for about a week, meaning that if book does not arrive during that week I will not be there.

Would it be safe to pre-order it? When is releasing date for this gem?
